Cape Town - Liverpool manager Jurgen Klopp believes his side never hit their full stride during Tuesday's Group C UEFA Champions League 2-0 defeat to Red Star Belgrade.
A brace from Milan Pavkov helped the Red-Whites to a surprise victory at the Rajko Mitic Stadium. The result could be a set-back for the Reds as they are currently on six points after four games, tied with Napoli in first place.
Paris Saint-Germain are in third on five points after they drew 1-1 with the Italian side on match-day four. Meanwhile, the Serbians are at the bottom on four points in the group.
Nonetheless, Klopp says that it was not his team's best performance although the hostile arena at the venue had little to do with matters on the night.
Speaking after the game, he said: "For us it was not clicking, it was not easy. It's really difficult then to find your mojo back, really difficult to do the right thing in the right moment, or naturally, because you always try to solve the problem actually.
"We gave them too many set pieces before they scored, so they could kind of train it. The second goal was kind of out of the blue, we had the ball and gave it away. That is not cool in a game like this, in an atmosphere like this, in a situation like this. It was a blow.
"I don't know. It was good, a good football atmosphere, I don't think it would have been impossible to perform to be honest. It was not to be afraid, it was a football atmosphere. Whatever they were saying we don't understand, it was only loud.
"But I don't know exactly. The atmosphere, singing-wise, noise-wise was not a problem, but the atmosphere after the second goal especially in the whole club, on the way in to the dressing room at half time they were all in a very positive mood."
The Merseyside-based outfit are next in action in the competition when they face PSG on 28 November at the Parc des Princes.
